Who Needs to File a Tax Return?
Not everyone needs to file a tax return in Ireland. You must file under self-assessment if you:
- Are self-employed (sole trader, freelancer, contractor)
- Are a company director
- Have non-PAYE income with taxable net income of €5,000+ per year, OR total gross income of €30,000+ per year
- Have rental income exceeding the thresholds above
- Want to claim tax refunds for medical expenses or other reliefs
Important Note
You must file even if you don't owe any tax because your income is reduced by losses, capital allowances or other tax reliefs.
Which Form Do I Use?
Form 11 (Self-Assessment)
Deadline: 31 Oct (paper) or mid-Nov (ROS)
Use Form 11 if you're self-employed, a company director, or have significant non-PAYE income. This is the main self-assessment form.
Form 12 (PAYE Employees)
Deadline: Anytime for previous 4 years
PAYE employees use Form 12 to claim refunds or report additional income under €5,000. You can file through myAccount at any time.
